CCIE IS-IS MPLS Lab

Posted by

>I’ve created a few labs for use with my CCIE studies until I get some workbooks from IPExpert. I’m going to be posting these periodically. Here is the first lab …

LAB001 Topology

1 IGP Routing
1.1 IS-IS Routing
Configure routers P1, PE-2, PE-3, and PE-4 using IS-IS.
  • Use area 43.0204
  • The loopbacks on these routers should be reachable by one another
  • The links PE-4 to PE-3 and PE-3 to PE-2 should be both L1 and L2 links.
  • The links PE-4 to PE-1 and PE-1 to PE-2 should be only L2 links.
  • Eliminate the DR election on each of the links.
2 PPPoE
2.1 Configure PPPoE between CE-5 and CE-7.
  • CE-5 will be the “server” and CE-7 the “client”
  • Use CHAP authentication with a username/password of ccie/ccie.
  • CE-7 should obtain its IP address via DHCP. This address should always be 12.1.57.7.
3 MPLS
3.1 Core MPLS configuration
  • Enable LDP between P-1, PE-2, PE-3, and PE-4.
3.2 VRF Configuration
  • Configure Serial2/0 on PE-3 and PE-4 to be in VRF Blue
  • Configure OSPF between PE-3, CE-5, CE-7, and PE-4.
  • Configure Serial2/0 on PE-2 to be in VRF Red
  • Configure RIPv2 between PE-2 and CE-6
3.3 MP-BGP L3VPN Configuration
  • Using MP-BGP configure a L3VPN connection between PE-3 and PE-4
  • P1 should act as a route-reflector for these routes
  • The loopback addresses from CE-5 and CE-7 should be advertised into this VPN on both PE-3 and PE-4.
  • CE-5 should prefer the L3VPN connection between PE-3 and PE-4 to reach CE-7’s loopback address. Do NOT use static routes.
  • CE-7 should prefer the L3VPN connection between PE-3 and PE-4 to reach CE-5’s loopback address. Do NOT use static routes.
3.4 Central Service L3VPN Configuration
  • Using MP-BGP configure a L3VPN such that CE-5 can reach CE-6’s loopback address through PE-4.
  • Using MP-BGP configure a L3VPN such that CE-7 can reach CE-6’s loopback address through PE-3.
  • CE-6 should only have the loopback addresses of CE-5 and CE-7 added to its routing table via the PE-2 to CE-6 RIP process.
